The total of 12 steam locomotives of the class Pt 2/4 H were built by the Krauss company for the Royal Bavarian State Railroad between 1906 and 1908. They were used on routes in Bavaria for light and fast passenger trains .
The vehicles all had bulk firing with a drop funnel for one-man operation. Doors in the front and rear walls and transition bridges made it possible to get from the train to the locomotive. The locomotives built in different series exhibited considerable structural differences in some cases, primarily the design of the driver's cab.
The Deutsche Reichsbahn took over all machines of this type and added them to their inventory as the 71 2 series . Due to their very good running properties, the last machines were only taken out of service after 1948.
